Patent CA-2012229-A1 (CA)
Inventor: TODA MINORU
IPC: H01S3/06
Filed: 1990-03-15
Abstract: A surface emitting grating is coupled to an optical amplifier and has grating elements tilted non-normal relative to the amplifier optical axis. The angle of tilt in one embodiment is such that the grating reflections are refracted out of the amplifier region. The amplifier may have a tilted light receiving end serving as an input port in a second embodiment to cause internal reflections from the grating to be reflected to an amplifier boundary at an angle greater than the critical angle to cause the reflections to pass out of the amplifier region.      In the latter embodiment, the grating tilt angle is minimized to reduce the surface emission beam ankle tilt from the normal to a relatively small angle.

Title: Rotary grate for a solid fuel furnace
Inventor: CHENARD MARK R
IPC: F23H9/00
Filed: 1990-04-19
Abstract: A ROTARY GRATE FOR A SOLID FUEL FURNACE       Abstract of the Disclosure The present invention discloses a rotary grate for a solid fuel fired furnace which allows ash, cinders and clinkers to be removed from the burning fuel mass, without reducing or stopping the combustion process.  A plurality of parallel water cooled rolls supports the burning fuel mass.  The rolls are grouped into pairs of rolls, each pair of rolls having a drive roll and a driven roll.  Each pair of rolls are geared together such that rotation of the drive roll simultaneously rotates the driven roll.  Each roll has a plurality of protrusions about the circumference thereof, spaced down the length of the roll.  The protrusions pass, during rotation of the rolls, the protrusions on adjacent rolls in non-contacting relationship to crush any cinders, clinkers or other tramp material.  This action allows ash and the crushed material to pass between the rolls to an ash collection area beneath the rolls.  Each of the drive rolls are rotated by a reversible drive mechanism which incrementally rotates the rolls.

Title: Stabilized polypropylene fibers pigmented with red 144
Inventor: KLETECKA GEORGE
IPC: D06P1/642
Filed: 1990-05-15
Abstract: ABSTRACT OF THE DISCLOSURE      Excellent stabilization to bright sunlight, is ob-tained in polypropylene (PP) fibers pigmented with Red 144, by combining the pigment with N-(substituted)-l-(piperazin-2-one alkyl)-.alpha. -(3,5-dialkyl-4-hydroxyphenyl)-.alpha.,.alpha.-substituted acetamide ("3,5-DHPZNA" for brevity). Stab-ilization of the red color is obtained for as long as the PP fibers themselves are stabilized by the 3,5-DHPZNA. 3,5-DHPZNA is a known hybrid stabilizer having a hindered amine N-(substituted)-1-(piperazin-2-one alkyl) group at one end, and a hinderd phenol (3,5-dialkyl-4-hydroxyphen-y1) group at the other. This particular hybrid, containing a piperazinone group, combined through a disubstituted alpha carbon atom of the acetamide in a single molecule, affords the advantages of each group with respect to its stabilization of the fiber against degradation, but with-out the expected adverse interaction of each group with Red 144 pigment. With 3,5-DHPZNA and Red 144 pigment, essentially no secondary stabilizer is necessary. Red PP fibers so stabilized, exhibit an acceptably low level of discoloration (color faidng) due to degradation of the pigment, over the useful life of the PP fibers. When exposed to sunlight for 6 months in Florida at a 45° South exposure, the red PP fibers suffer essentially no loss of color due to degradation of the pigment. Retention of red color in articles exposed to sunlight over their useful life, is of great practical value in clothing and house-hold goods made from woven or non-woven fabrics of Red 144-pigmented PP fibers.

Title: Insulated exhaust pipe and method and means for producing and connecting same
Inventor: BAINBRIDGE DAVID W
IPC: B60K13/04
Filed: 1990-08-09
Abstract: Abstract of the Disclosure an insulated exhaust pipe comprising inner and outer spaced corrugated metallic tubes separated by a layer of low density refractory fiber insulation and strips of higher density refractory fiber insulation.  The pipe is made by adhering the insulation to the inner tube and inserting the insulated inner tube into the outer tube while rotating it so that the corrugations of the outer tube do not damage the insulation.  Attachment means for connecting a corrugated insulated pipe to an element in the exhaust system means include a conduit having a transverse lug which allows the conduit to be threaded into the pipe.  The end of the pipe is received in an end cap slidably mounted on the conduit.  A stop on the conduit limits relative movement of the pipe and conduit, permitting the connection between the pipe and conduit to be tightened.  A standard exhaust pipe can also be insulated by a flexible insulated tube comprising concentrically arranged inner and outer corrugated stainless steel tubes, the annulus between the corrugated tubes being filled with refractory fiber insulation.  The wall thickness of the corrugated tubes is in the range of 0.002 inch and 0Ø04 inch, which provides the insulated tube with sufficient flexibility to be trained over nonlinear portions of the exhaust pip.  The contact between the corrugations and the pipe assists in holding the insulated tube in place.  In addition, a flexible coupling is provided for connecting an engine manifold to an exhaust  pipe  in  order  to  relieve  torque. concentrically spaced flexible tubes, which have insulation filling the annular space between them, are connected to inlet and outlet tubes having interior ends located between the ends of the flexible tubes.   The inlet and outlet tube have enlarged upstream ends and smaller downstream ends.  By overlapping the interior ends of the inlet and outlet tubes, the tubes are able to have relative angular movement when the flexible tubes bend due to engine torque.  One or more separate tubes which also have enlarged and smaller upstream and downstream ends may be provided to overlap with the inlet and outlet tubes to allow bending of longer couplings.     ** TOTAL PAGE .001 **
